Mechanosensation is the ability to detect dynamic mechanical stimuli (e.g., pressure, stretch, and shear stress) and is essential for a wide variety of processes, including our sense of touch on the skin. How touch is detected and transduced at the molecular level has proved to be one of the great mysteries of sensory biology. A major breakthrough occurred in 2010 with the discovery of a family of mechanically gated ion channels that were coined PIEZOs. The last 10 years of investigation have provided a wealth of information about the functional roles and mechanisms of these molecules. Here we focus on PIEZO2, one of the two PIEZO proteins found in humans and other mammals. We review how work at the molecular, cellular, and systems levels over the past decade has transformed our understanding of touch and led to unexpected insights into other types of mechanosensation beyond the skin.

Background: Free radicals play a key role in spinal cord injury and curcumin has the potential to act as an antioxidant agent. Controlled delivery of curcumin can be achieved through encapsulation in bovine serum albumin to form nanoparticles, and acellular scaffold can bridge lesions and improve axonal growth in spinal cord injury.
Objective: In this study, we evaluated the antioxidant effects of the scaffold containing curcumin nanoparticles in the unilateral spinal cord injury model in male rats.

Mercury(II) ions (Hg) are one of the most common and highly toxic heavy metal ions, which can contaminate the environment and damage the human health. Therefore, the precise detection of trace Hg concentration is particularly important. Herein, gold nanoparticles-enhanced silver-coated hollow fiber (HF) surface plasmon resonance (SPR) sensor was developed for the highly sensitive detection of Hg ions.

Leishmaniasis, a disease caused by Leishmania parasites, poses a significant health threat globally, particularly in Latin America and Brazil. Leishmania amazonensis is an important species because it is associated with both cutaneous leishmaniasis and an atypical visceral form. Current treatments are hindered by toxicity, resistance, and high cost, driving the need for new therapeutic targets and drugs.

Kefir grains offer numerous health benefits, including boosting the immune system, alleviating digestive issues, and enhancing antimicrobial activity. They are rich in beneficial probiotic bacteria that promote gut health and support a balanced intestinal microbiota. "Beta-lactoglobulin (β-lg), a well-known milk protein," is used to create nanofibril structures that can serve as scaffolds.

Camels have unique morphological traits that enable them to adapt well to harsh conditions. This work aims to describe the vascular architecture of the camel retina and investigate its cellular components with a focus on the distribution of mitochondria in Muller cells and photoreceptors, using light and electron microscopy. The camel retina is euangiotic in which blood vessels extend in the inner retina from the nerve fiber layer to the outer plexiform layer.
